Analysis  Using  SAS 

The analysis of the data is performed using PROC TTEST of SAS. The SAS commands are given in the sequel.

Data Input:

For performing analysis, input the data in the following format. 

{Here Total number of male flowers per plant is termed as tmfppp, Number of  fruit (45 days) is termed as nfs45, Fruit weight (kg) is termed as fw, Fruit length(cm) is termed as fl, seed yield/plant (g) is termed as syp and Seedling length (cm) is termed as sl. It may, however, be noted that one can retain the same name or can code in any other fashion}.

/*To answer the question number 2 one has to perform by the one tail t-test. The easiest way to convert a two-tailed test into a one-tailed test is to take half of the p-value provided in the output of 2-tailed test  for drawing inferences. */
